Climate change is caused by the increasing emissions of ‘greenhouse’ gases from human activity. Predictions indicate that climate change could seriously affect the climate of the UK and of London and could impact many areas of life.

Climate change

Global warming has already begun to change London’s climate and the impact is likely to become more extreme. This section outlines how the weather is changing, what the government is doing and some tips on how you can make a difference.

How is London’s climate changing?

Below is a list of some of the key differences you might notice in the capital’s weather:

• Extreme weather (storms, heat waves etc.) is likely to become more frequent.
• Wetter winters.
• Hotter and drier summers, prolonged heat and increased wind intensity.
• Risk of flooding could increase with more rainstorms and raising sea levels - leading to more frequent closures of the Thames Barrier.

What impact will climate change have?

As well as posing some dangers and being uncomfortable, the changing climate will have some dramatic practical effects:

• By the 2080s, London’s summer extreme temperatures could be comparable with those of present-day New York. This will dramatically increase the amount of electricity needed in summer as we try to keep cool.
• London is one of the driest capital cities in the world, with available water resources per head of population similar to that of Israel. Climate change could reduce the amount of water available and increase demand in summer, so increasing the risk of drought.
• Climate change is expected to affect investments both in the UK and abroad, impacting on London’s Stock exchange and the UK economy.

What’s being done to prevent climate change?

The Greater London Authority, Government and London boroughs are working to reduce emissions of 'greenhouse' gases and promote the use of renewable energy and more energy efficient building design. You can find out more about the plans and progress in preventing climate change at the London Climate Change website.

What can I do to help?

It’s a big problem but individuals can make a big difference. Here are some of the things you can do to help:

• Get your house well insulated and cut down on your heating - turning down a thermostat by just one degree centigrade saves an amazing 10% on your fuel bill each year!
• Switch to a green energy supplier.
• Use public transport instead of your car and if you can, try to walk or cycle as much as possible.
• Use energy efficient light bulbs.
• Try to fly less – consider holidays in the UK!

Those are just some ideas to get started. For more suggestions and advice on getting green, go to the London Climate Change website.
